This contemporary home in Noe Valley was a firehouse in a former life.

The firehouse, built in 1909, was known as Engine 44. It served the neighborhood for 50 years, before it became the home of artist Mark Adams and his wife, Beth Von Housen, according to the listing. It now belongs to a young tech entrepreneur who bought the property from another owner about two years ago.

A renovation in 2007 transformed the firehouse into a sleek residence without sacrificing its historic charm. “There’s so much character that’s still incorporated into the house,” said listing agent Carrie Goodman of Sotheby’s International Realty.

The home is dotted with bits and pieces of its past, including a brass fire pole, fire bells, zinc-clad doors and reclaimed Douglas fir floors. “I think the firs really warm up the house,” said Goodman. A spiral staircase leads to a tower that was once used to dry hoses. The room is now a lounge that overlooks Noe Valley.

The 6,045-square-foot house has four bedrooms, three full bathrooms and two partial bathrooms. There is a staircase made of glass and reclaimed lumber in an atrium that floods the home with natural light. An elevator services all four floors.
